lb all whom. it may concern."

3e it known that I, WILLIAM l. Barrannonr, a citizen of the UnitedStates, residing .at Bettendorf, in thecounty of Scott and of dumpingcars, and particularly -to'that.

type of dumping cars, whose bodies are .adaptedto be lifted from theirtrucks.

The objects of my invention are to provide such a construction of thebody-bolsters that the tilting of thecar-body can be ac-' com lishedwithout afiecting the relation of the ody-bolster to the truck-bolster,and so.

that when tilted the body will main- .tainedin its tilted position bythe automatic actionoia gointed strut or brace, and so that whenthisrace is broken and the car resumes itsnor'mal vertical position, itfiwlll be mamtalned and locked in said position byhooks thatautomatically engage the ends ofs'tfhel cradlespart of the bodybolster.

This I accomplishgtiy the means hereinafter described and "asparticularly pointed out in the claims; v v

In the drawings :-.-'Figure 1 iso planview of the underside. of one halfof a dump car embodying my invention. Fig 2 ice transverse verticalsection taken on dotted line-2, 2, Fig. 1.

innerside extends, in the horizontal plane of the floor of the car,inward toward the body-bolster, to a point about midway be tween thetransverse plane of the pivotof the truck and the end of the car, andits rear edge portion is provided with a depressed seat in which thelower flanges of the ceniersills are seated and suitably secured so'thatFig. 8. is a View similar to Fig 2 showing the-ear in its tiltedposition. Fig 4 The end-sills are, preferably, made their. uppersurfaces are in the same plane as the upper surface of said extension 0.

The body-bolster comprises two parts, which may be the bolster properand the cradle..: Thebolster consists, preferably, of a transverse castmetal beam extending from side-sill to side-sill of the car, thecentral'part of which is rectangular in cross section and tubular andthe portions between this central part and its ends are channeled andthetlower edges of the side-walls of said channeled portions are flangedinward. The top of this bolster proper consists of a flat upper plate,D, the upper surface of which is in the same horizontal plane as theupper surface of-the upper flanges of the center-sills and'side-sills,and the lower portionthereof has its parallel sidewalls d separated adistance less than the width of said top-plate, D, and'is bellieddownward so that the depth thereof is greatest at its center of lengthand so that the lower side thereof is curved to enable it to rock fromone side to the other on its lower edges. The lower side edges of saidbolster are provided with recesses E, which are, preferably, arranged inpairs'in the same transverse plane, and so that the pairs will be equaldistances apart. The center of length of the upper portion of thisbolster is provided "with a suitable transverse depressed seat f ofsuiiicient dimensions to permit the passage of the center-sills, that isof such depth that the upper surfaces of the upper flanges of'saidsills-will be-in the same horizontal plane as the upper surface of thebolster.

The ends of the bolster are seated upon the inturned lower flanges ofthe Zbar side-sills, and are suitably secured thereto by rivets orotherwise. and the floor. G of the car, which consists, preferably. ofa. single sheet metal plate, extending from end to end and'sidc to sideof the ear, is riveted to the center-sills. the side-sills and lwlstersof the underfranw.

The bolster rests upon and is seated in a cradle consisting of atransverse channeled beam H, the bottom plate or web of which extends ina straight horizontal plane (min end to end,'and is n-uvidr-d at ininner angles of the lower flanged edges of its sidewalls withprotuberanciis that constitute. teeth orxcogs 9 that are adapted to beengaged by the recesses E in the lower edges.

Thus,limit o the diagonal slot j of'the link I, "when the car is in itsnormal verticalposi" .and propup the raised side of the car. tion thecentral cogs and recesses will be in When it is desired to restore thecar to its engagement, and when the car is tilted the normal horizontalposition, shaft a is rocked o engagement of said cogs and recesses willso thatarm'h pulls'linkl toward the adprevent the car-body from slippingupon jacent side of the car,- and the latter, pulling said cradle H andthus injure their proper Jon the upper member-90f the brace, movesrelation.
